From: Leon Romanovsky <leonro@mellanox.com>
Infiniband part of mlx5 driver can be compiled as a module
or as a part of bzImage (compiled in). In the second case,
the call to request_module will return an error -ENOENT.
It will cause to a misleading print "failed request module
on mlx5_ib".
This patch removes this print, In order to comply with mlx4.
Fixes: f66f049fb738 ("net/mlx5_core: Request the mlx5 IB module on driver load")

Firmware representation of the firmware version on the health buffer has
changed for newer device. The representation in the initialization
segment does not and will not change. In addition, we print the health
buffer firmware version as a raw hex number.

From: Eugenia Emantayev <eugenia@mellanox.com>
Implement query and set functionality for MTPPS and MTPPSE registers.
MTPPS (Management Pulse Per Second) provides the device PPS capabilities,
configures the PPS in and out modules and holds the PPS in time stamp.
Query MTPPS is supported only when HCA_CAP.pps is set and modify is supported
when HCA_CAP.pps_modify is set.
MTPPSE (Management Pulse Per Second Event) configures the different event
generation modes for PPS. Supported when HCA_CAP.pps is set.

This patch enables the 1PPS IN and 1PPS OUT support according
to the advertised HCA capability. Single pin may be configured
to one of the above mutual exclusive functions via standard
Linux tools and APIs. For example, testptp open source application.

To: David S. Miller; +Cc: netdev, Mohamad Haj Yahia, Saeed Mahameed
From: Mohamad Haj Yahia <mohamad@mellanox.com>
Today when the driver enter to promiscuous mode or vlan
filter is disabled, we add flow rule to receive any c-taggd
packets, therefore s-tagged packets are dropped.
In order to receive s-tagged packets as well we need to add
flow rule to receive any s-tagged packet.
Fixes: 7cb21b794baa ('net/mlx5e: Rename en_flow_table.c to en_fs.c')

PCAM: Ports capabilities mask register.

PCAM and MCAM registers will provide information regarding firmware
support for different features, in order to avoid cases where new driver
combined with old firmware results in syndromes (for ex. PCIe counters
before this patchset).

Introduced registers will expose capabilities of new registers and
features related to port/management.
Driver will query MCAM and PCAM in order to avoid failing on old

On load_one, we now cache our capabilities registers internally, similar
to QUERY_HCA_CAP. Capabilities can later be queried using macros
introduced in this patch.

Use ethtool -S to query physical layer statistical counters including:
- rx_symbol_errors_phy: Number of symbol errors that were not corrected
by FEC correction algorithm or that FEC was not active on this interface.
- rx_corrected_bits_phy: Number of corrected bits according to active
FEC (RS/FC).

Reorder update stats flow to update most important counters last,
to get more accurate results.
New update order:
- PCIe counters
- Port counters
- Vport counters
- Queue counters
- Software counters
